Description

Technical Field

[0001] This utility model belongs to the field of metallurgical equipment technology, and more specifically, it relates to a slag pot self-locking mechanism and a tilting machine. Background Technology

[0002] Currently, the slag treatment method in the metallurgical industry is to use a tilting machine to automatically feed slag pots into the treatment container, achieving safe, convenient and stable operation, while also solving the problem of the operating rate of workshop cranes.

[0003] To ensure the stability of the slag pot on the tilting machine, a drive mechanism, a linkage mechanism, and a locking arm are usually installed on the tilting machine. The drive mechanism drives the locking arm in linkage through the linkage mechanism, and the slag pot is fixed by clamping the trunnion with the locking arm.

[0004] In existing technologies, the rotation angle of the locking arm is typically controlled by the drive stroke of the drive mechanism. That is, as the drive stroke changes, the locking arm rotates accordingly. When the drive mechanism reaches its maximum stroke, the locking arm clamps precisely onto the trunnion to achieve locking and positioning of the slag pot on the tilter. However, in actual operation, due to equipment installation deviations, equipment vibration, and the inherent precision of the drive and linkage mechanisms, relying solely on the drive mechanism's stroke control can lead to situations where the locking arm clamps the trunnion before the drive mechanism reaches its maximum stroke. If the drive mechanism continues to operate, this could damage or deform the linkage mechanism or the locking arm. Alternatively, if the drive mechanism reaches its maximum stroke but the locking arm has not fully clamped the trunnion, the slag pot will exhibit poor stability on the tilter, posing a significant safety hazard. Utility Model Content

[0005] The purpose of this utility model is to provide a self-locking mechanism for slag pots, which aims to solve the problem that when the rotation angle of the locking arm is controlled by the driving stroke of the driving mechanism, the locking arm or connecting mechanism may be damaged, or the slag pot may be unstable.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a slag pot self-locking mechanism, for installation on both sides of the trunnion of the tilting machine, comprising:

[0007] A locking arm, the middle part of which is rotatably mounted on the tilting machine, and the upper end of which has a locking part adapted to the trunnion;

[0008] A drive mechanism, which is hinged to the tilting machine and located below the locking arm;

[0009] A linkage mechanism, the middle part of which is used to rotatably set the tilting machine, the upper end of which is hinged to the lower end of the locking arm, and the lower end of which is hinged to the drive end of the drive mechanism;

[0010] A limiting mechanism is provided on the tilting machine and located between the locking arm and the drive mechanism. The limiting mechanism is used to block the linkage mechanism so that the locking part of the locking arm clamps the trunnion.

[0011] In one possible implementation, the limiting mechanism includes:

[0012] The mounting part is disposed on the tilting machine;

[0013] A limiting part is provided on the mounting part and facing the linkage mechanism, and the limiting part is used to block the linkage mechanism.

[0014] In one possible implementation, the mounting part is adjustable in position along the front-rear direction of the tilting machine, and the limiting part is adjustable in position along the height direction of the mounting part.

[0015] In one possible implementation, the limiting part is provided with a limiting protrusion on the side facing the linkage mechanism, and the linkage mechanism is provided with a limiting groove adapted to the limiting protrusion.

[0016] In one possible implementation, the limiting groove has chamfered corners on both sides of the groove opening.

[0017] In one possible implementation, the width of the limiting groove is greater than the width of the limiting protrusion.

[0018] In one possible implementation, the linkage mechanism includes:

[0019] A crank, the middle part of which is rotatably mounted on the tilting machine, the first end of which is hinged to the drive end of the drive mechanism, and the limiting mechanism is used to block the crank;

[0020] A connecting rod, the lower end of which is hinged to the second end of the crank, and the lower end of the locking arm is hinged to the upper part of the connecting rod.

[0021] In one possible implementation, the second end of the crank and the lower end of the connecting rod form a first hinge portion, the first hinge portion being adjustable in position along the length direction of the connecting rod, and the lower end of the locking arm and the upper end of the connecting rod form a second hinge portion, the second hinge portion being adjustable in position along the length direction of the connecting rod.

[0022] In one possible implementation, the locking part is an arc-shaped groove formed at the upper end of the locking arm, the arc-shaped groove facing the trunnion, and the curvature of the arc-shaped groove is adapted to the curvature of the outer wall of the trunnion.

[0023] The beneficial effects of the slag pot self-locking mechanism provided by this utility model are as follows: Compared with the prior art, the slag pot self-locking mechanism includes two sets, which are respectively installed on both sides of the trunnion of the tilting machine. The locking arm, connecting rod mechanism, and driving mechanism of the slag pot self-locking mechanism in the same set are sequentially hinged, and the locking arm, connecting rod mechanism, and driving mechanism are respectively rotatably installed on one side of the tilting machine. The driving end of the driving mechanism drives the connecting rod mechanism to move, and the connecting rod mechanism drives the locking arm to rotate. When the locking part at the upper end of the locking arm clamps the trunnion on the same side of the slag pot, the limiting mechanism just blocks the connecting rod mechanism, and the connecting rod mechanism can no longer move, thereby keeping the state of the locking part clamping the trunnion stable. The slag pot self-locking mechanism provided by this utility model uses the limiting mechanism to block the connecting rod mechanism so that it cannot continue to move, thereby keeping the state of the locking part clamping the trunnion stable. This method is mechanical self-locking, which has better stability than the method of controlling the stroke of the driving mechanism, reduces the risk of damage to the locking arm or connecting mechanism, and improves the stability of the slag pot.

[0024] This utility model also provides a tilting machine, including the aforementioned slag pot self-locking mechanism.

[0025] The beneficial effects of the slag pot self-locking mechanism provided by this utility model are as follows: Compared with the prior art, the tilting machine uses the above-mentioned slag pot self-locking mechanism, and therefore has the same beneficial effects as the slag pot self-locking mechanism. Through mechanical self-locking, the slag pot is stably installed on the tilting machine, reducing the risk of damage to the locking arm or connecting mechanism. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

It is not intended to indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the specific protection scope of the present invention.

[0038] Please see Figure 1 and Figure 2 The present invention provides a self-locking mechanism for a slag pot. The self-locking mechanism for a slag pot is used to be installed on both sides of the trunnion 600 of a tilting machine, and includes a locking arm 100, a drive mechanism 400, a linkage mechanism, and a limiting mechanism 500.

[0039] The middle part of the locking arm 100 is rotatably mounted on the tilting machine, and the upper end of the locking arm 100 has a locking part 110 adapted to the trunnion 600; the drive mechanism 400 is hinged to the tilting machine and located below the locking arm 100; the middle part of the linkage mechanism is rotatably mounted on the tilting machine, the upper end of the linkage mechanism is hinged to the lower end of the locking arm 100, and the lower end of the linkage mechanism is hinged to the drive end of the drive mechanism 400; the limiting mechanism 500 is mounted on the tilting machine and located between the locking arm 100 and the drive mechanism 400, and the limiting mechanism 500 is used to block the linkage mechanism so that the locking part 110 of the locking arm 100 clamps the trunnion 600.

[0040] This utility model provides a slag pot self-locking mechanism. Compared with the prior art, the slag pot self-locking mechanism includes two sets, which are respectively installed on both sides of the trunnion 600 of the tilting machine. The locking arm 100, the connecting rod mechanism, and the drive mechanism 400 of the same set of slag pot self-locking mechanisms are sequentially hinged, and the locking arm 100, the connecting rod mechanism, and the drive mechanism 400 are respectively rotatably installed on one side of the tilting machine. The drive end of the drive mechanism 400 drives the connecting rod mechanism to move, and the connecting rod mechanism drives the locking arm 100 to rotate. When the locking part 110 at the upper end of the locking arm 100 clamps the trunnion 600 on the same side of the slag pot, the limiting mechanism 500 just blocks the connecting rod mechanism, and the connecting rod mechanism can no longer continue to move, thereby keeping the state of the locking part 110 clamping the trunnion 600 stable. The present invention provides a slag pot self-locking mechanism, which uses a limiting mechanism 500 to block the connecting rod mechanism from continuing to move, thereby keeping the locking part 110 clamping the trunnion 600 in a stable state. This method is a mechanical self-locking mechanism, which is more stable than the method of controlling the stroke of the drive mechanism 400, reduces the risk of damage to the locking arm 100 or the connecting mechanism, and improves the stability of the slag pot.

[0041] The drive mechanism 400 can be any one or a combination of a pneumatic cylinder, hydraulic cylinder, or electric push rod, selected according to the actual working conditions. The cylinder body of the drive mechanism 400 is hinged to one side of the tilting machine. As the drive end of the drive mechanism 400 extends or retracts, the linkage mechanism moves accordingly. The drive mechanism 400 adapts to the tilting machine by utilizing its hinged position, preventing locking. Here, a pneumatic cylinder is preferred for the drive mechanism 400. Pneumatic cylinders offer stable driving force, high piston rod displacement accuracy for precise positioning, and can withstand large loads. They are compatible with supporting both large and small slag pots. Furthermore, pneumatic cylinders have high heat resistance, allowing for stable operation even in high-temperature metallurgical environments, ensuring the stability of the production process.

[0042] Please see Figures 3 to 5The limiting mechanism 500 includes a mounting part 510 and a limiting part 520. The mounting part 510 is a rectangular frame structure, which is fixed to the tilting machine by bolts. The limiting part 520 is a block structure, which is installed on the mounting part 510 and faces the side of the linkage mechanism. As the linkage mechanism moves, the limiting part 520 will abut against the side of the linkage mechanism, thereby preventing the linkage mechanism from continuing to move. At this time, the locking part 110 at the upper end of the locking arm 100 clamps the trunnion 600. The locking arms 100 on both sides move synchronously, thereby locking the slag pot on the tilting machine.

[0043] Preferably, the mounting part 510 is adjustable in position along the front-to-back direction of the tilting machine, and the limiting part 520 is adjustable in position along the height direction of the mounting part 510. The mounting part 510 has two strip-shaped holes in the front-to-back direction at its top, with at least two bolts for connecting the tilting machine passing through the same strip-shaped hole. The mounting part 510 is adjusted front-to-back by using the bolts in the front-to-back direction through the strip-shaped holes. A connecting plate 530 is fixed to one side of the limiting part 520. The limiting part 520 is longitudinally positioned in the middle of the connecting plate 530. The connecting plate 530 has two strip-shaped holes in the longitudinal direction, located on either side of the limiting part 520. At least two bolts for connecting the tilting machine pass through the same strip-shaped hole. The connecting plate 530 drives the limiting part 520 to adjust its height by using the bolts in the longitudinal strip-shaped holes.

[0044] Please see Figure 6 A limiting protrusion 521 is provided on the side of the limiting part 520 facing the linkage mechanism. The limiting protrusion 521 is integrally formed with the limiting part 520. The linkage mechanism is provided with a limiting groove 310 that matches the limiting protrusion 521. When the limiting protrusion 521 is fully inserted into the bottom of the limiting groove 310, the locking part 110 of the locking arm 100 locks the trunnion 600. Through the limiting cooperation between the limiting protrusion 521 and the limiting groove 310, the displacement of the limiting protrusion 521 along the length direction of the linkage mechanism can be limited, thereby improving the stability of the locking arm 100.

[0045] Specifically, the limiting groove 310 has guide angles 311 on both sides of the groove opening, which allows the limiting protrusion 521 to rotate smoothly into the limiting groove 310.

[0046] In addition, the width of the limiting groove 310 is greater than the width of the limiting protrusion 521, which can prevent locking when the limiting protrusion 521 rotates into the limiting groove 310. A gap is formed on both sides of the limiting protrusion 521, allowing it to have a certain amount of displacement even when locked within the limiting groove 310. This can buffer the vibration of the slag pot on the locking arm 100, reducing the risk of damage to the linkage mechanism and the locking arm 100.

[0047] Please see Figure 1 and Figure 2The linkage mechanism includes a crank 300 and a connecting rod 200. The middle part of the crank 300 is rotatably mounted on the tilting machine. The first end of the crank 300 is hinged to the drive end of the drive mechanism 400. The limiting mechanism 500 is used to block the crank 300. At this time, the limiting groove 310 is opened on the crank 300. The lower end of the connecting rod 200 is hinged to the second end of the crank 300, and the lower end of the locking arm 100 is hinged to the upper part of the connecting rod 200. When the crank 300 and the connecting rod 200 are collinear or are within the self-locking angle range, the force along the length direction of the connecting rod 200 can no longer cause the linkage mechanism to move, that is, it reaches the dead point position. At the dead point position of the linkage mechanism, the locking part 110 of the locking arm 100 just clamps the trunnion 600, which can realize that the slag pot is in a stable self-locking state.

[0048] Please see Figure 1 and Figure 2 The second end of the crank 300 and the lower end of the connecting rod 200 form a first hinge portion. The position of the first hinge portion is adjustable along the length direction of the connecting rod 200. A conformal elongated hole is formed in the middle of the connecting rod 200 along its length direction. A first adjusting plate 210 is provided across the conformal elongated hole on one side of the conformal elongated hole connecting to the second end of the crank 300. The first adjusting plate 210 and the end of the conformal elongated hole form a first hinge hole 230. A first hinge shaft 320 is provided at the second end of the crank 300. The first hinge shaft 320 passes through the first hinge hole 230 from one side, which can realize the hinge between the crank 300 and the connecting rod 200. In addition, the first adjusting plate 210 is adjustable along the length direction of the connecting rod 200, which can realize the adjustment of the size of the first hinge hole 230 to accommodate first hinge shafts 320 with different outer diameters. Furthermore, the lower end of the locking arm 100 and the upper end of the connecting rod 200 form a second hinge portion, the position of which is adjustable along the length of the connecting rod 200. Two second adjusting plates 220, spaced apart and spanning the conformal elongated hole, are provided on one side of the locking arm 100. A second hinge hole 240 is formed between the two second adjusting plates 220. A second hinge shaft 120 is provided at the lower end of the locking arm 100, extending through the second hinge hole 240 from one side, thus enabling the hinge between the locking arm 100 and the connecting rod 200. Additionally, both second adjusting plates 220 are adjustable along the length of the connecting rod 200, allowing adjustment of the size and position of the second hinge hole 240 to accommodate second hinge shafts 120 with different outer diameters.

[0049] Furthermore, the locking part 110 is an arc-shaped groove formed at the upper end of the locking rotating arm 100, with the arc-shaped groove facing the trunnion 600, and the curvature of the arc-shaped groove matching the curvature of the outer wall of the trunnion 600. To ensure the stability of the locking between the arc-shaped groove and the trunnion 600, an anti-slip layer is provided on the inner wall of the arc-shaped groove. This anti-slip layer is made of refractory cotton and is bonded and fixed. The surface of the refractory cotton layer is roughened to increase the friction between the arc-shaped groove and the trunnion 600 while ensuring its refractoriness, thus ensuring the stability of the slag pot.

[0050] Based on the same inventive concept, this utility model also provides a tilting machine that uses the above-mentioned slag pot self-locking mechanism. Therefore, it has the same beneficial effect as the slag pot self-locking mechanism. Through mechanical self-locking, it ensures that the slag pot is stably installed on the tilting machine, reducing the risk of damage to the locking arm 100 or the connecting mechanism.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
